VARIABLES Notes

 Are factors that change  There are 3 variables in an experiment:  Manipulated (independent)  Responding (dependent)  Controlling Variables…

 In order to carry out this experiment…  You will need to grow plants at different temperatures. Will house plants grow faster if you make the room warmer?

 Variable that you purposely change…  Temperature of the room Manipulated Variable

 The variable or factor that may change as a result of the manipulated variable. These are your results.  How fast the plants grow. Responding Variable

 Factors or conditions that must remain the same so that the results of the experiment are valid.  Type of soil  Amount of soil  The amount of fertilizer Controlling Variable
